Yes, we are talking about libration.

Well as I already proved, field rotation is why the moon looked like a "u," not libration. Thanks for agreeing with me.

You are very welcome, Mr Astro:-) Ok lets call it field rotation. I think the terms are not important:

Terminology IS important. Field rotation is not libration. Libration is a minor effect compared to field rotation, and has a much longer periodicity than field rotation.
we are looking at the vid,

What part of your video shows libration, not field rotation did you not understand? What part of field rotation depends on observer position did you not understand? Which part of they only showed libration did you not understand? It's impossible for the video to show what the moon's apparent orientation will look like from your specific location from a non-polar aligned perspective; that depends on your location and varies from person to person.
P.S. I checked your link, but no Moon vids from last week.

Bullshit, the link takes you straight to the relevant video. Everyone, watch this from 9 minutes on:

Dr. Astro,
1. you claim above , that "field rotation is why the moon looked like a "u," not libration"
I found the definition of field rotation, and it says:
"Field rotation is the apparent rotation of a celestial object in the field of view of a telescope during the course of the night. All objects in the eyepiece field or on the camera’s image will move in arcs. It’s usually either ignored or not noticed for visual observations, but cannot be ignored for photography." [link to www.celestron.com]
That is FIELD ROTATION refers to viewing an object in a TELESCOPE. Our observations of the U-MOON made directly, with naked eyes, no telescope. The animation, that we compare our observations to also simulates a naked eye observation. That concludes you cannot explain the U-Moon by Field Rotation.
2. I watched your video, but your verbal notes offered no explanation HOW the field rotation effects the phenomenon we are talking about.

Please verify you're human:
